Journey through Madness

Delving into UnderMountain from top to bottom!

Undermountain

Undermountain is a many floor complex running below Mount Waterdeep (hence it’s name) and much of Waterdeep itself. For decades it has served as a testing ground for adventurers, and most of them have not returned – leading to Undermountain’s notorious reputation.

Undermountain is unique in that it had become Halaster’s personal laboratory. Of course, many of the denizens objected to this at the time, but Halaster simply killed them all. Halaster, being rumored to be quite world-weary, had a major hobby in coming up with complicated and bizarre traps, and collected the most unusual of monsters for his experiments and for fighting the never-ending stream of hopeful adventurers seeking to become the victors of Undermountain. Coupled with the naturally unstable nature of his magical experiments, Undermountain is a place reeking of volatile magic and the other-worldly.

As the SpellPlague and recent events have only served to exasperate the situation, even experienced adventurers will find themselves pitted against the unfamiliar. Only a strong cohesive team has any hope of making it through alive.

It is common knowledge that Undermountain was originally split into 13 floors, however, the experiment suspected to have killed Halaster and the SpellPlague have had a substantial renovating effect on the place.

It’s a labyrinth! Not only that, but it’s made of crystal-clear walls, floors and ceilings. Halaster’s Aqitocrun, a treasure chamber in which he stores prized possessions can be found in the heart of the labyrinth.

Halaster’s magical altars, ritual chambers and personal chambers reside here. The traps and monsters are the most deadly of all of Undermountain, and his treasure is said to lie here. It is rumored to link to the Underdark as well.
